so, my chain loosened fast! it popped off the for second time this afternoon (i meant to tighten it before i left), got caught on the crank peg and ate one of my chainring teeth. also, two of my chainring bolts bit the dust today. so these are my questions?:

when will my chain stop going slack?

how unsafe is it to ride with a missing tooth?

am i going to be replacing chainring bolts like crazy, now?

any other maintenance i should look out for?

ride it and i can check it out tonight.

iffin' your not using a qr, and you use enough chain tension, your chain should never fall off. perhaps you should look for irregularities on the chain and cr.
use stainless cr bolts and they won't break.
cr should be fine as long as it's straight.

Is your chain coming loose because your rim is moving?
I had this problem when i had quick release... Since i've switched to bolts, I just tighten the eff out of it and have very little slip, i still have some occasionally, but just have to reset the wheel every couple days instead of everytime i go to get on it. Though, even w/ the quick release I only had the chain pop once, and that was when i was riding brakeless... haha. Nothing like riding downhill through portland's downtown w/ no brakes.

the bolts on my current crank keep coming loose as well. I am just buying a new crank... so i don't care. the one i have is garbage.

Hey, it wasn't planned.
I went to skid stop and bent the QR , which made my chain go slack and pop off.
Luckly I caught mostly green lights except where there was this taxi, he wasn't happy, i was guessing by the honking...
after that it leveled out and i figured i'd try stopping w/ my shoes.. which doesnt' work well w/ clipless.
then I proceeded to throw my bike around downtown because I couldn't tighten the QR. good times. I proceeded to lock my bike up and go get drunk. the end.

but i did put my brakes back on shortly afte.r

yeah, we should definitely convert it to a solid axle.

once again, as a recent person dealing with this happening, the questions to ask are:

1) is the wheel slipping in the dropouts because of inadequate tension? you ain't big enough to bend properly adjusted qr nuts, lassie.

2) what about bad chainline, old chain, and a ramped chainring? that's been a problem for me?

3) do you have an ovalized chainring with a really tight spot on the chain?

4) also worth checking out, make sure the seatstay isn't cracked, that will cause the chain to flex.

if you need a new chain, get a single speed Z chain, mobius stocks them, i love mine!

leah, your easiest solution is to get a bolt on qr. they substitute an allen nut fo the qr's cam mechanism. this will allow you to tighten it with a wrench, and not have to convert it to a solid axle.

i think i might even have one. i'll try to bring it tonight.

Too late, it's all solid and bolted now.

As I posted a while back, I bent the QR axel on my rear wheel, so I took the axel from my front wheel as a temp bolt axel.
I tried taking the QR from a old 27 inch to put in my front rim, and after doing so and putting everyone back on, the bolt doesn't spin free from the rim...

I am remembering that at the wrench party we used her drop-out width as the basis for the chain line. We may have neglected to check if her hub was actually the same width. It would be worth re-checking the chainline too.

yeah, i figured it was incorrect.
DO you have have words that they just look wrong for some reason?

It happened there.

Oh, right, I didn't know you used the dropout width. The dropouts seemed wider than the axle today by a few mm, so the chainline could be off by 2-4mm I guess.

But we'll see how it goes...

And the 41/16 is a better ratio in my opinion. Way faster.

Josh, dude.
Read your fucking posts before you hit the "Submit" button.
Each one of your posts in this thread alone has at least two syntactic errors.

Some of the sentences just don't make any damn sense, viz.

Of course the damn rim is moving. That's what bike rims do when the bike to which they are attached is used properly.

Here's your sign...

Uh, I can't remember where It was uploaded. I am not sure why it's not working? I'll have to check when I get home. I can't access that site from work.

When I do scheduling work, I am pretty busy multi-tasking many things at once. so, I'm usually in a hurry.
I will be sure to try and check in the future. ;)

and the rim moving, I ment as in is it sliding in the dropouts. not is it turning...

Rims never touch the dropouts unless I live in an alternative universe. In my universe we have Axles in the droupouts.

Bit of terminology for you here.

The wheel is a unit composed of the following parts:
1) Hub
a) Axle
b) Bolts or QR mechanism as appropriate for attaching the wheel as a whole to the bike frame.
b) Bearings
c) One, possibly several cogs (rear wheel only).

2) Spokes and nipples

3) Rim (may include rim tape)

4) Tire

5) Tube

It is theoretically possible for your rims to touch your dropouts due to massive deformation of the rim but this precludes your wheel/rim assembly spinning freely.

It's also possible that quantum effects are making it difficult to accurately locate your rim in space. I have no idea how to fix this.

First procure a box, one cat, and a small ampule of uranium isotope...
